Yes please! Funny it isn't an option already (without customize). Would like to make user profiles public but lots of them have their phone numbers added and don't want Google (and others) to index them.

I tried URL filtering in ACP and blocked some image hosting sites. My suggestion is that if somebody posts a blocked URL, they should get notified about it. For example if member posts an image URL and that domain is blocked by suite, the post will be empty. Suite does not state it was blocked so member will edit post or even do another post with the same content. After that they blame admins that something is broken.

All of these red or gray banners are for your own good. Don't know why's there so much dissatisfaction around it. Only admins see those. Other hand, when something happens to your Suite people are asking "why i didn't get notified about new security release" or something. But it's only my humble opinion

When I first saw Activity Stream here, I was thinking like "Oh God whyyyy?". I believed my members will never be OK with it. At first I was against it myself. My members are from 16 - 70 y.o but most active users are mid 30's so I was ready for a battle. But... What turned out - they haven't had any questions or problems with it. Not any! I was like... "It has to be a conspiracy or something". Now I'm used to it myself.

As much as I know IPB have stored original gallery files in previous versions also. They are useful if you want to rebuild gallery images.
I see your concern about disk space. You may change the Maximum Image Size in Group Settings to reduce original image size for future uploads. It won't apply to your old files tho.
Speaking about myself, I once found original gallery files useful when I wanted to remove watermark on images. But I'm not worried about disk space either

No, post author did not change but topic author changed from mine to someone elses.
My common sense thought that first post will not change and others will sorted by topic date after first post.
This kind of topic hijacking is a bit funny My first reaction was cmd+z

Hey! I have some questions about topic splitting. I'm a bit confused and should it work this way after all.
I made a topic on my forums and needed to transfer some posts into that topic. I used "split" in old topic but the result was that my post in new topic went to last position and topic starter changed to person who made the earlyest post from splitted posts.
Should it work that way? Or is it a bug?

Would like to know that as well?!
One of the hosts I know stated on their FB page that they will not offer PHP7 anytime soon because they have their own control panel and upgrading it would be too much work 🤔 It's some cheap (and unreliable for me) host anyway. My own host has made a rule that they will make PHP versions upgrade on first monday of every month if any of them have come out.

What I find PM system should have or needs to improve by feedback from my members: 1. Topics pane on the left lacks participants information. If I'm the starter and I replied last, theres no way to know whom I'm taking to without opening message. Theres only information about how many members are in specific conversation if I roll over the number. If I have many conversations with the same title, it's a bit confusing. Solution should consider mobile version as well. 2. If theres more than 1 page of replies, clicking on title it takes me to the first page. At least my members find it should take you to the last or have an opportunity to select last page from topics pane. 3. Believe it's a bug but sometimes it opens topics pane on the top and message body at the bottom. On mobile I mean. If I do refresh, it removes topics pane and works like it should. Problem occurs mostly when selecting message from popup window when I click on envelope icon. It's a bit annoying because theres too much scrolling. 4. On mobile, if I reply to a conversation it won't move conversation at the top of the topics pane. After page reload it's at the top. Members have asked an option to select multiple conversations at the time to delete as well but I saw it's already done with 4.1.
